Investigating strategies to reduce CO_2 emissions from the power sector of Taiwan

摘要

This paper investigates strategies to reduce CO_2 emissions from the power sector of Taiwan. A multi-objective mix integer model for power generation strategy in Taiwan is proposed. A power supply problem with integer constraints on lowest power generation to meet the practical operation of power unit is also presented. This model can be used to plan future power units' expansion strategy, as well as to study the effect of CO_2 emission constraints. Then this model is used to investigate optimal strategies for stabilizing CO_2 emissions to the desired level from the power sector in Taiwan; these accounted for about 40% of CO_2 emissions in the country in 2000. Real operational data from the Taiwan Power Company are used for testing the model effectiveness. In addition, recommendations are made for implementation.
